Fill out the form and produce the origami cd-wallet with your tracks listed the way that you want them...
The PDF created uses Origami notation for folding (dashed lines: mountain fold; dotted lines: valley fold). Figure it out from there. Very elegant. Be sure to, when you print, turn off scaling completely through your printer preferences. This may be on by default. Once I figured out to turn that off, the fit was perfect! I like the little spines you get - something that was missing for me with previous paper-based sleeve designs.
